Pauline Ocean uses her medium gifts to solve clients’ problems with the dead—and Mack, her resident ghost, helps her. However, while her psychic abilities enable her to solve mysteries and steer troubled spirits toward the light, they often put her in grave danger…

After a night of poker and partying, Pauline’s medium powers are in jeopardy. She must change her lifestyle or lose her ability to communicate with ghosts. If that happens, Mack will be lost to her forever.

Pauline hopes that a weekend in a health spa will restore her full powers. There, she meets Amanda Jordan, an indie movie producer with a dark secret—and her own paranormal problems.

When Amanda hires Pauline to work at a movie location—a haunted mansion in the Hollywood Hills—the resident spirits prove to be very challenging. Now, Pauline’s in danger, and so is Mack. As Pauline’s professional ethics are tested, bigger threats arise…

A dangerous adversary lies in wait—but will Pauline and Mack be able to send the troubled spirits into the light? And can they do it without losing Amanda to the dark side?
